Michael Lanigan 1871 or 1873 Tipperary

I am trying to find background details on my Grandfather Michael Stanley Lanigan born Ireland 1873 (only possible match in Dublin General Register office is 1871) Parents - James and Margaret Lanigan were farmers.This is confirmed on my grandfathers marriage certificate. Family anecdotes say he came from Tipperary.There are no family records of any siblings but who knows?!! If anyone can help I'll be very grateful.
